First up is Rescue Beauty Lounge Aqua Lily vs. BB Couture Calico Jack. Aqua Lily is from the Fan Collection from Spring 2012. Aqua Lily is on the left and Calico Jack is on the right. You can see that while similar, they are not dupes. AL is brighter and more vivid. CJ is a lighter and more muted shade of turquoise and includes lots of whitish glass fleck type glitters in with the pink shimmer. This is more visible in the shade photo below. Both have excellent formulas.

And the other comparison is Rescue Beauty Lounge Réveillon vs. BB Couture La Buse. Réveillon came out just this past fall/winter in the Fan 2.0 Collection.
Réveillon is on the left and La Buse is on the right. Again, they are definitely similar but not dupes. The RBL is a silvery, more crisp blue and has more shimmer particles. La Buse has a more grayed tone and mixes in a few whitish glass flecks with a more subtle shimmer. I love both of these and couldn't choose between them.

There you have it! You can purchase Rescue Beauty Lounge nail polish from their website for $20 each. You can get BB Couture lacquers from their website for $10.95 each. Do you prefer one over the other in these comparisons? I am glad I own all four, I like things about each of them!
